See the example URL for what I mean. In this instance the HTML writer has
forgotten the equals sign. I believe it's pretty clear that the intention was
id="foo" not id"foo"="". In quirks mode, you can just put the = back in. In
strict mode, the attribute should be ignored as invalid, and not appear in the
DOM.

Similarly for single quotes and mixed-up quoting (one of each).
I'm not sure about attribute names, but HTML says of attribute values:

The attribute value may only contain letters (a-z and A-Z), digits (0-9),
hyphens (ASCII decimal 45), periods (ASCII decimal 46), underscores (ASCII
decimal 95), and colons (ASCII decimal 58).

I would contend that the same character set restrictions be applied to
attribute names (unless they are actually defined somewhere).
